cros_write_firmware: support 32K SPL blobs properly
When calculating BL1 + SPL padding size to the nearest 8K boundary,
the code assumed SPL to be of 14K in size. In fact it could be either
14K (potentially coming in a 16K envelope) or 30K (potentially coming
in a 32K).
BUG=none
TEST=manual
. after this fix it is possible to create a flasher for snow (32K
SPL platform). Both of the below commands produce working
flashers and the DUTs boot from SPI after flashing.
$ emerge-daisy chromeos-u-boot chromeos-bootimage exynos-pre-boot && \
cros_write_firmware -b daisy -w sd:. -D -M exynos \
-i /build/daisy/firmware/nv_image-snow.bin \
--dt /build/daisy/firmware/dtb/exynos5250-snow.dtb \
-F spi -U /build/daisy/firmware/u-boot.bin
